HOOP-DRAWING APPARATUS.

Specification of Letters Patent.

Patented Dec. 25, 1906.

Application filed October 19,1905. Serial No. 283,517.

To It whom it may concern:

Be it known that I, SToNEwALL JAoKsoN CAROLAND, a citizen of the United States, residing at Glarksville, in the county of Montgomery and State of Tennessee, have invented a new and useful HoopDrawing Apparatus, of which the following is a specification.

This invention relates to the production of wooden hoops for hogsheads, barrels, and the like, and has for its object to provide an improved device of this character which is arranged tofacilitate the drawing therethrough of the stock, so as to trim the latter on opposite sides to the desired thickness in a very simple and expeditious manner.

A further object of the invention is to enable the satisfactory flattening or skiving of one end of the hoop without stopping the movement of the material through the apparatus. It is also proposed to provide for effectually guiding the work to the knives and to have the apparatus under the complete control of the attendant.

\Vith these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure l is a top plan view of a hoop-drawing apparatus of the present invention. Fig. 2 is a longitudinal sectional view thereof. Fig. 3 is a cross-sectional view on the line 3 3 of Fig. 1. Fig. 4 is a detail perspective view of one of the knifeadjusting wedges.

Like characters of reference designate corresponding parts in all of the figures of the drawings.

The present device includes a base or body 1, which is rigidly secured upon the top portion 2 of a suitable frame or stand, the latter being considerably longer than the body or the base, so as to support the work during its progress through the apparatus. The top 2 is supported adjacent its opposite ends upon posts 3 and 1, so as to support the appara- -tus at a conveniently accessible height. At what will be termed the forward end of the body or base the latter is provided with an opening 5, in which is received a pair of upstanding knife-blades 6, each of which is substantially triangular in cross-section and has its cutting edge directed toward therear of the device. Rearwardly and downwardly inclined braces 7 extend between the tops of the knives and the base or body 1, there being a bolt 8 piercing the tops of the knives and the braces, so as to connect these memers.

As best indicated in Fig. 1 of the drawings, it will be noted that the outer faces of the knife-blades are beveled or inclined, while their adjacent faces are substantially parallel, there being upper and lower spacingblocks 9 interposed between the knifeblades. Each of these spacing-blocks is preferably wedgesl1aped, as clearly indicated in Fig. 4 of the drawings, and has a longitudinal slot 10. The bolt passes through the slot of the upper spacing-block, and another bolt 11 pierces the lower end portions of the knife-blades and passes through the slot of the lower spacing-block and also transversely through the base or body 1. By driving the wedges the spacing of the knifeblades may be regulated according to the desired thickness of the hoop to be drawn. In addition to the braces 7 there are also braces 12, which incline downwardly and outwardly from the tops of the knife-blades to the base or body 1 and are pierced at their upper ends by the bolt 8, whereby the knife-blades are rigidly supported in a simple and convenient manner.

In front of the knife-blades there is a Workguide made up of a pair of longitudinallydisposed flat spring-bars 13, which are terminally pivoted to the base or body 1, as at 14, from which they converge toward the knife-blades and have their free ends provided with antifriction-rollers 15. About midway between the ends of these guide members there is an arched bar 16, straddling the members and pierced through its opposite sides by set-screws 17, which are designed to bear against the respective guide elements to maintain the necessary tension thereon. A stop-arch 18 is carried by the base or body and interposed between the guide members 13. Still another arch 19 straddles the guide members 13 between the arch 16 and the knife-blades, so as to prevent upward displacement of the work.

Immediately in front of the knife-blades the base or body 1 is provided withanopening 20, there being an opening 21 formed through the'top 2' of the stand and registering with the opening 20. Working in the opening is an upstanding yoke or fork 22, the bottom of which normally rests against shoulders 28, formed in the opening 20, soas to limit the downward movement of the fork. A stem or bar 24 depends from the fork through the openings 20 and 21 and has or 'bodyl between the guide members 18 and is-pushedtherebetween and also between the knife-blades,the forward end of this wooden strip having been thinned or tapered by 'In'eans-of an adz or other implement, so as to enable the convenient passing of the forward end of the strip between the knife-blades. Afterthusbeing set a suitable clamp (not shown) is connectedto theforward end of the work, and a "single horse or a *team is 'hitched'tothe clamp and driven away-from theapparatus, so as to draw the strip ofwood between the knife blades, which latter shave 'o'if opposite sides of the strip and reduce'the latter t0 the desired thickness.

By-refereneetoFig. 3 of-thedrawings it will-be noted that the knife-blades areset to converge upwardly, and when the rear end of the work approaches the knives the attendiupward convergence of the knife-blades the rear end portion of the work will be reduced 'ina' very simple and eflicient manner. 'Dur- 'ing the passage of the work through the apparatus -it is held against upward displacement by the arch19,-and therefore the fork '22 can be elevated only when the rear endof the workhas c'learedthe arch 19. In other words, the arch 19 acts as a gage'to'hold'the "work in lowered position until the end of the work moves out "from under the arch 19, afterwhich the fork 22- is operated to elevate the work, whereby to'reduce the extreme end thereof.

"-When the work -is passing between the 'knives, =-each"-knifeof course trims or cuts a lower =-ren'd portion secured to the body or base 1, as at 29, and its upper 'end'piercedlby the fastening '8.

The purpose of thesedeflectors is to direct the shavings outwardly, and thereby prevent choking of the knifeblades.

To accommodate the device to Work of different thicknesses, it is proposed to provide wedges 9 of different sizes, and by the provision of the slot 10 each wedge may be driven in between the knife-blades, so as to obtain slight adjustments of the latter without requiring the substitution of a wedge of a different thickness. By preference a branch slot lOintersects one edge of the wedge and the slot 10, so asto-enablethe engagement of the wedge with the adjacent .bolt without removingthe latter.

While itis not absolutely necessary, I-propose to employ upstanding "guide-rollers 30, carried by the base or'body 1 and spaced at opposite sides of thepath of thework as it passes between theknives 6, wherebyany lateral strain of the power uponthework will nottend towedge the latter-againstone of-the knives. The upper-ends (if-the guiderollers arejournaled inbrackets- 31, carried by the tops of therespective deflecting elements 28.

Having thus described the invention, what is claimed is 1. A device of the class described comprisfitted between the blades and-piercedby t -e fastening.
